PRINTING AND FOLDING MACHINE.

I b'PECIFICATION forming part of Letters Patent No. 711,742, datedOctober 21, 1902.

Application filed June 14:, 1901. $erial No. 64,512. (No model.)

To all whom, it may concern:

Be it known that I, WALTER ScoTT, a citi- 'zen of the United .States,and a resident of Plainfield, in the county of Union and State of NewJersey, have invented a certain new and useful Improvementin PrintingandFoldingMachines, of which the following is a specification. I

The present invention relates toweb-perfecting printing and foldingmachines, and has for one object the production of copies containing anyof a large number of different numbers of pages or sheets.

Another object is the association of and folding together as one'productof long and short sheets, and other objects, as will appear hereinafter.

To these ends the invention consists of fea tures of construction andcombinations of devices hereinafter described, and more particularlypointed out in the appended claims.

Forms of the invention are illustrated in the accompanying drawings,forming part of this specification, in which- Figure 1 is a sideelevation, with parts omitted, of a machine in which the invention isembodied. Fig. 2 is an end View of delivery mechanism included in theinvention. Fig. 3 is a View of a modification of the invention. Fig. 4is a sectional view of a paste-applying device.

In the drawings, the referencesAB O designate parts of threeweb-perfectingprintingpresses arranged one above another in any suitableor known form of framework, such framework being shown in partonly, anda. b c are the webs printed upon by said presses.-

D is a rotating sheet-carrier provided with a plurality ofsheet-receiving surfaces, two in the instances shown in Figs. 1 and 3,with sets of sheet-retainers, as pins d, there being one set for eachsurface, for holding the leading ends of the sheets or webs on theleading ends of the said surfaces with two folding-blades e, whichrevolve about an axis f eccentric to that of the carrier D, and with twolongitudinally-arranged cutting-grooves g, just behind which are thesheet-retainers. There is a male cutting-cylinder E coacting with thecarrier D, and the two sever full length or long sheets from the web orwebs other transverse margin and the columns of the plate-cylindersrunning along the platecylinders. It is obvious, however, that'the havemore than one cutting-blade. A cam may draw in the pins (1 as theseapproach the line of tangency between the webs and the per as the latterlies on the carrier and just before-the web or webs are severed by thecutting-cylinders D E. In the form of the invention illustrated in Figs.1 and 3 the cylinder D is twice the size of the cylinder E; but it isremarked that these proportions are not essential to the invention. Acam 2 opsheets as these are folded off by the blades e.

In the embodiment of theinvention shown inFig. 1 the blades e aremounted in frame 3, journaled on the shaft f, similarly to the mountingfor the rotating frame carrying the folding-blades shown in LettersPatent of the United States dated December 1, 1896,

in is rotated turn for turn with the carrier D, differing in thatrespect from the bladecarrying frame of my said Letters Patent. Eachblade 6 is rigidly connected with its own gear 4, and these gears 4 meshwith gears 5, journaled on frame 8, and the gears 5 mesh with fixedgears 6 on the framework of the machine. The inechanism'bywhich theblades (2 are operated is similar to that shown at Fig. 17 of LettersPatent No. 171,196, dated December 14, 1875, to which reference is made.Adjacent to and driven from the carrier D are folding rolls or. jaws 7between which the blades 6 push or fold the sheets from the carrier D,and 8 .are tapes running on rollers or pulleys 9 and the rolls 7 andcarrying the sheets out for further folding and delivery. The drivingpower may be transmitted to a shaft 10, on which is a gear meshing witha gear 11 on the carrier'D, whereby the carrier is driven, and thecylinder E is driven by carrier D in the usual manner.

The'presses A B O are adapted to print upon wide webs or two pagesabreastupon each web, the columns running along the cylerates the pins dto cause them to release-the" led thereto, the cutting occurring alongevery carrier D may have more than two sheet-receiving surfaces and thatcylinder E may carrier D and release them to pierce the paand numbered572,280; but the frame f here- ICO inders thereof. splitting the webslongitudinally along the central margins thereof, or two single-widthwebs placed edge to edge may be used in place of the wide webs abovedescribed. The web 12 passes from press B about roller-guides 15 andover tapes 16, the slitter 14 dividing it longitudinally, as above setforth, and one longitudinal section thereof may pass about turners orparallel bars 17 and guide-rollers 18 and be associated with the otherlongitudinal section at the rollers 19. I A paste-applying device mayapply paste alongalternate transverse margins of that section of the web2) which passes direct to the rollers 19'from the last guide 15, andsaid paster 20 may apply paste along such margins of the entire web I)when the longitudinal halves thereof are not associated in the mannerabove set forth. The device 20 shown comprises a rotating cylinder, overwhich the web 1) passes, a blade mounted within said cylinder to becapable of a rocking motion, and

associated sections.

means for causing said blade to take paste from a fountain and apply italong alternate transverse margins, as above described, the rockingmotion of the blade permitting its withdrawal inside the cylinder, so asto skip alternate transverse margins, as will be understood. Mechanismfor so moving said blade may comprise any mechanism suitable .for thepurpose, as a cam rotating in time press 0 about guides 15 and under aslitter 14. When the turner-bars 17 are in use, at least one-half of theweb 0 passes to them around a roller 22 and is associated with half ofweb I) if half thereof is also run about said bars 17, and when bars 17are not in use the whole web 0 passes direct from the last guideroller15 therefor to the rollers 19, a pastor 20 being used, if desired, toapply paste along alternate transverse margins of the Web 0, whichmargins register with those margins of web I) along which paste may beapplied, as above.

The press A may be. run at the same surface speed as the press B bybevel-gears A or at one-half of the said surface speed of press B bybevel-gears A. When the press A is run at the same surface speed as thepress B, the web (1 passes about guide-rollers 14 represents slittersfor be torn loose in a known manner.

reached. The webs a Z7 are associated at the rollers 19 and passtogether therefrom as a multiple-ply web to the cylinders D E. Thebevel-gears A and A which are on the vertical shaft, may be disengagedfrom the gears on the cylinder of press A in the usual way. When the weba has one-half the speed of the web I), it is taken to cutting-cylindersF G and cut into sheets half the length of the sheets cut by thecylinders D E. The cylinders F G may be capacitated to sever wide websormerely to perforate them, as may be desired. When it is desired toassociate the sections of a wide web a, one section thereof is takenabout the parallel turner-bars 24 and guide-rollers-25 and is laid uponthe other section thereof, which lies upon the tapes 16?. It ispreferred that the cylinders F G wholly sever the sheets from the web orwebs, and the cylinder G may be provided with a set of pins just behindthe cutting-groove therein for carrying the end of the web or websaround under side of the carrier D, the end of the web reaching thecarrier 3' ust as the cylinders sever the sheet therefrom, orthecylinders F G may merely perforate the web and the sheet to acceleratethe speed of said sheets and to lay them upon the sheet-receivingsurfaces of the carrier D, the shaft 10 is provided with or carries acylinder 27, which is provided with a gripping-bar 28, which coacts withthe carrier D to clamp the leading ends of the sheets just as thecylinders F G out the web or associated web-sectionsand to suddenlyincrease their speed to that of the carrier D. If the cylinders F Gmerely perforate the web, the bar 28 and carrier D also detach thesheets from the web. The tapes 26 are carried around the carrier D to apoint where the shortlength sheets will reach the cutting-point ofcylinders D E, or, rather, will pass between said cylinders'D E, beforethey are released from the action of the tapes 26 and the carrier D,guides 21 retaining the sheets against the carrier D between the tapes26 and the cylinder E. The cylinder 27 andtapes 26 are driven at twicethe speed of the cylinders F and G, which are geared together. Thehalfsheets so fed forward pass under the web I) with their leading endsunder those margins of the web I) along which the pastor 20 appliespaste, the short sheets preferably overlapping the central lines of suchmargins of the web I), as shown at Fig. 6 of Letters Patent No. 655,354,dated August 7, 1900, so as to be folded by the blades 6 and so that thecuttingblade of the cylinder E will not cut strips from the tails of theshort sheets. For the purpose of securing register of the printed matteron the long and the short sheets, the cylinders F G are set to cut theshort sheet with In order a wider margin atits leading end than at therear end.

Other presses may be placed above the presses A B C, and the web or webs23 from such other presses may be run to the folding mechanism, as willbe understood.

Assuming that one or more full-width webs pass directly to the cylindersD E to be cut and folded as above described, there are two side-by-sidesheets folded off between the rollers 7 and carried forward by the tapes8 over folding-rollers 29 and under foldingblades 30, there being onepair of rolls 29 and blade 30 for each longitudinal half of the web orwebs associated upon the carrier D. The blades 30 are fast upon shafts31, journaled in the arms 32, fast on shafts 33, which are journaled inthe frame of the machine. The shafts 31 are provided with gears 34,which mesh with gears 35, journaled on the arms 32, and gears mesh withgears 36, fast to the fixed framework of the machine. -The gears 34 3536 are so proportioned that the blades 30 revolve at least once betweensuccessive intrusions thereof between the rolls 29. The shafts 33 aregeared with the shaft 10 by a train of gears 12 13, bevel-gears 37, andpinions 38. The shafts 33 are cut away at 39 to allow the blades 30 topass freely during their rotation on shafts 31. The sheets folded byblades 6 and rolls 7 are run out over rolls 29 by the tapes 8 and areforced down between the rolls 29 by the blades 30, suitable stops 29being used for the sheets, and thus receive folds at right angles to thefolds given by the blades e and rolls 7. The mechanism by which theblades are operated is similar to that shown at Fig. 17 of said LettersPatent No. 171,196, to which reference is made. The sheets coming fromrolls 29 may be associated by tapes 40 41 42, guides 40 43, theassociation taking place at therolls 44, the paths from the pairs ofrolls 29 being equal in length, and such associated sheets may passdownbetweentapes 40 and adjustable guides 47 to and be delivered by arotating S-fly 45 upon traveling tapes 46, a roller 49 being used inconjunction with the tapes 40 to feed the sheets down properly, or theguides 47 may be so adjusted as to cause thecopies coming down fromvrolls 44 to pass along the tape-path 41 to 48 to another folding anddelivery mechanism, or the guides 43 may so set as to cause the copiescoming down from the rollers 29 at the right in Fig. 2 to pass out alongtape-path 42 to 50 to a separate folding and delivery mechanism placedabove that to which tape-path 41 to 48 directs the sheets. In this waythe copies produced by one half the web-presses may be delivered at onepoint and those produced by the other half may be delivered at anotherpoint above the first, or both may be associated and delivered together.

In the modification shown at Fig. 3 the blades e are fixed to the frame3 and the frame is mounted to rotate upon an axis eccentric to that ofthe carrier D; but the frame is carried around by the carrier,wherebythe blades move in and out radially of the carrier, being similar inthis respect to the blade shown in Letters Patent of the United Statesgranted June 12, 1877, to Tucker, and numbered 192,035. The blades 6 mayforce the sheets between rollers, as in said Tucker patent; but thearrangement shown in Fig. 3 is preferred. In this a cylinder H isprovided with a longitudinal groove and with grippers for gripping thefold of the sheets and carrying the sheets around and delivering them tothe tapes 8, guides 51 directing the sheets be tween the tapes.

The press A may be driven at half or at full speed by gearing, such asshown in my Letters Patent of the United States, dated August 7, 1900,and numbered 655,354, or adjustable bevel-gearing A A such as shown inFig. 1'of the drawings hereof, may be used for these purposes. The usualtakeup rolls for securing register of the printed matter upon the websand for keeping tapes taut may be used; also the rollers 7, 19, 29, and44 are adjustable toward and from each other. It will also be understoodthat pins, grippers, and other moving parts for which no operatingmechanisms are shown may be operated at the desired times by knownmeans, such means being here omitted for the sake of clearness in thedrawings.
